REID, OF CLEVELAND, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE EATON AXLE & SPRING COMPANY, OE CLEVELAND, OHIO, A CORPORATION 0F OHIO CLOSURE STRUCTURE Application led March 5, 1928. Serial No. 259,139.

This invention relates to closures such as are used for radiators, splash pans and other parts of automobiles and particularly where the closure for one reason or another should be applied to the deviceto be closed in one definite angular relation.

The object of the invention is to provide a closure of this kind in which the closure vice applied for one kind of use on an auto-4 mobile, and particularly as a closure for a radiator; Fig. 2 is a detail sectional elevation showing the closure applied to a neck;`

Fig. 3 is a bottom plan view of the closure; and Fig. 4 is a plan view of the neck.

The desirability for the present invention arises under varying circumstances where, for

some reason, it is necessary to apply a clo' :surel 1n onel definite angular position to a de vice to be closed. Thus, the closure for the splash or dust pan at the front of an automobile is sometimes ornamented, as with a figure or design, and it is desirable to have the figure or design stand upright when the closure is in its final locked position. Again,

the closure for a radiator sometimes carries an ornament or even the temperature indlcator or motor meter A shown 1n Fig. 1, Whose face must be presented to the driver of the car and because of which a definite angular relation 'is necessary.

In the drawings, 1 represents the neck or other portion of any such device to be closed.

It is of ordinary form in the sense that it is equipped to take a cap or closure secured to it by bayonet or other quick detachable operation, such as by being provided at its open end with an inwardly extending flange 2 bent back at its inner end edge' and having depending portions 3 which :form cams for cooperation with locking devices on the cap. The several cams are separated'by openings or gate-ways 4, and all of the parts so far described may be of any usual construction such as shown in my prior Patent No. 1,593,847, granted July 27 1926.

The cap comprises a body portion carrying bly held at its outer edge in the outer shell1 4 as by crimping the metal around its periphery at 8. The central portion of the disk 1s depressed into cup form at 9. This cup shaped body suitably supports any suitable number p of locking lingers. In the arrangement shown theV locking fingers are three in'jnumber marked respectively, a, b and o. They project radially outwardly from a central disk portion 9 firmly riveted or otherwise non- 'rotatably secured to the inner face of the cup and contained in its chamber, the several 'lingers being bent upwardly and extending outwardly through slots or openings 10 in the cup wall. These outwardly projecting finger ends ride along theedges of the cams `3 and in rotating the cap to its closed or locked position produce more or less compression of the lgasket 1l lying between the Harige 2 of the neck and the annular portion? of the cap plate. v

The definite angular relation between the cap and neck members, according to the present invention, is obtained and assured by assigning to one or more of the locking ngers and to the recess or gate-way through which -it passes, a definite shape distinguishing it from others. Thus, as shown in Fig. 3, the several fingers a, b and c have different shapes, finger b, for example, having a reentrant notch or recess 12 so that it fits one and only one of the recesses 4 in the neck. Obviously, the severalfingers may be made of.'

quite different shapes from those shown in the closure member adapted to be introduced through said openings for cooperation with said cam means for locking the closure member on the neck member, the contour of one'of said fingers being similar to the 'contour of said one opening but different from the contour of another of said fingers, whereby said closure member may be applied to the neck member in only one position.

In testimony whereof I hereby afiix my signature.

drawings, but the gates or openings 4 will always be matched to the fingers. .As a result, it is possible to apply the cap to the neck only in one position and when it is rotated to its final locked position, the exposed part able to pass through the recess for finger '6.

What I claim is:

1. In combination, a device having a neck membenand a closure member for application-to said neck to close the device, said members being provided with cooperating locking parts adapted for quick connection and disconnection by rotation of said closure'member relative to said neck member and positioning means associated with said locking parts whereby the closure may be applied to the neck in only one angular relation thereto.

2. In combination, a device to be closed provided with a neck member, and a closure member therefor, cam means on the neck member terminating in openings leading thereto, locking fingers on the closure member adapted to be introduced through said openings and to the cam means and cooperating therewith for locking the closure on the neck member, said fingers and openings being shaped to match eachother and some fingers differing in shape from others, whereby the i closure member may be applied to 'the neck member in only one position.'

3. In combination, a device having a neck member, cam means on said neck member terminating in openings providing access to the under side of said cam means, the contour of one of said openings belng different from thel contour of another of said openings, a closure member for application to said neck member to close the device, and locking fingers on said
